[bgpd] Fix infinite loop in community_str2com
2006-03-30 Paul Jakma <paul.jakma@sun.com> * bgp_community.c: (community_gettoken) Unknown token should return NULL, to give a strong indication to callers that the token no longer can be parsed, otherwise callers looping on this function may have a hard time ending their loop. (community_str2com) While loop around community_gettoken appears to have been coded thinking that break statement would break from the while{}, hence it could never exit for unknown token case. Fix it to do..while, so it can use the NULL result from community_gettoken easily.
